Need solution!

I have a math problem I would really like help on, I have racked my brain but can not do it.

I make 43,000,000 a day and it increases 5.2 mil or 7.8 mil a day depending on which property I buy. I want to buy property which cost 30 mil which goes up 2 mil after each purchase and another property that costs 45 mil and goes up 4 mil after each purchase. The income for the one that goes up 2 mil after each purchase gets me 200,000 every 55 mins. and the 4 mil one gets me 300,000 every 55 mins. The properties started at 20 and 40 mil.. I can buy up to 10 properties at a time. I am taking the monies to buy the properties from the income I make off of them. The problem comes when to buy and which one to buy at which times and how many at a time.

This sounds like a problem from "mob wars" in facebook...

Basically this can be done anyway you want.

To calculate how long it would take for an investment to pay off, simply use this:

The higher the income, the faster you make money after the place pays itself off.

Thanks, I will try and make that work. I think you are saying always by the higher priced property with the higher income. I was thinking that at a certain point you should switch to the other one. You are really close as to the game, it's Mobsters on myspace.
